Answer: 8t + u -7

Explanation:

The perimeter of a triangle is calculated by adding all the sides together. Therefore, in this case, the perimeter of the triangle will be:

= (2t + 2) + (6t - 7) + (u - 2)

= 2t + 2 + 6t - 7 + u - 2

= 2t + 6t + u + 2 - 7 - 2

= 8t + u -7

The perimeter will be (8t + u -7)cm.
